The system case holds and protects the computer's internal components from external elements. The motherboard connects and supports crucial parts like the CPU, memory, and input/output ports. The power supply converts electrical energy and powers the computer. A heat sink dissipates heat from electronic devices to prevent overheating. A graphics/video card generates and sends output images to displays. Common ports include USB ports for connecting external devices. The processor processes and handles data. The network card enables data transfer between the computer and network. The hard disk drive stores and provides quick access to large amounts of data. Optical drives like CD/DVD drives read and write data to discs using lasers. RAM is temporary memory that stores and supplies data fast

2. System Case
The primary function
of the computer
system unit is to hold
all the other
components together
and protect the
sensitive electronic
parts from the
outside elements.

3. Motherboard
A motherboard is one
of the most essential
parts of a computer
system. It holds
together many of the
crucial components of
a computer, including
the central processing
unit (CPU), memory
and connectors for
input and output
devices.

4. Power supply
Power supply is an
electronic device that
supplies electric
energy to an electric
load. The primary
function of a power
supply is to convert
one form of electrical
energy to another and,
as a result, power
supplies are
sometimes referred to
as electric power
converters.

5. Heat sink
A component designed
to lower the
temperature of an
electronic device by
dissipating heat into
the surrounding air. A
heat sink without a fan
is called a passive heat
sink; a heat sink with a
fan is called an active
heat sink.Heat sinks
are generally made of
an aluminum alloy
and often have fins.

6. Graphics card
A video card connects
to the motherboard of
a computer system and
generates output
images to display.
Video cards are also
referred to as graphics
cards. Video cards
include a processing
unit, memory, a
cooling mechanism
and connections to a
display device.

7. Ports
A port is an
interface between a
computer to
another computer
or peripheral
devices, a mainly
used port is the
USB port.

8. Processor
The processor is
a the part of the
computer which
processes or
deals with the
data and
processes in the
system.

9. Network card
The network
card allows data
to be transferred
between the
computer and
network.

10. Hard Disk
Drive (HDD)
A hard disk is part of a
unit, often called a
"disk drive," "hard
drive," or "hard disk
drive," that stores and
provides relatively
quick access to large
amounts of data on an
electromagnetically
charged surface or set
of surfaces.

11. CD-ROM/DVD-
ROM DRIVE
CD-ROM/DVD-
ROM DRIVE is a
device that uses
photo diodes to
detect reflecting
lights on optic discs
and uses a laser to
read or write data.

12. RANDOM ACCESS
MEMORY
Memory or RAM is a
computer hardware
that serves as a
temporary data
storage. Memory
works by storing and
supplying the
necessary data it needs
fast processor to be
processed into
information.

13. Central
Processing Unit
The central processing
unit (CPU) of a computer
is a piece of hardware
that carries out the
instructions of a
computer program. It
performs the basic
arithmetical, logical, and
input/output operations
of a computer system.
The CPU is like the
brains of the computer -
every instruction, no
matter how simple, has
to go through the CPU.
